Fragmentation of Data in Large-Scale System For Ideal Performance and SecurityEditor IJCATR
Cloud computing is becoming prominent trend which offers the number of significant advantages. One of the ground laying
advantage of the cloud computing is the pay-as-per-use, where according to the use of the services, the customer has to pay. At present,
user’s storage availability improves the data generation. There is requiring farming out such large amount of data. There is indefinite
large number of Cloud Service Providers (CSP). The Cloud Service Providers is increasing trend for many number of organizations and
as well as for the customers that decreases the burden of the maintenance and local data storage. In cloud computing transferring data to
the third party administrator control will give rise to security concerns. Within the cloud, compromisation of data may occur due to
attacks by the unauthorized users and nodes. So, in order to protect the data in cloud the higher security measures are required and also
to provide security for the optimization of the data retrieval time. The proposed system will approach the issues of security and
performance. Initially in the DROPS methodology, the division of the files into fragments is done and replication of those fragmented
data over the cloud node is performed. Single fragment of particular file can be stored on each of the nodes which ensure that no
meaningful information is shown to an attacker on a successful attack. The separation of the nodes is done by T-Coloring in order to
prohibit an attacker to guess the fragment’s location. The complete data security is ensured by DROPS methodology
Comparative Study of Optic Fibre and Wireless Technologies in Internet Connec...Editor IJCATR
Most of the activities going on in the world today demand information and data sharing in one form or the other.
Consequently, the Internet and its connectivity has gradually become a household concern. The connection to the Internet requires
physical transfer of signal (data/information) from one point to another. This can either be through physical medium (wire) or through
the air (wireless). This paper a comparative study of Fiber Optics and Wireless Technologies in Internet connectivity seeks to identify
which of the two technologies is better for signal transmission in terms of bandwidth utilization, performance, reliability, cost
effectiveness, resilience, and security. The study adopted the use of secondary sources for the sourcing of materials. A lot of journal
articles, research publications, testbooks, white papers and many more were critically studies and comparatively analysed. It was clear
that both media have hitches and challenges. The study showed that although initial cost of acquisition is an inhibitive factor for fibre
optic connection, unlimited bandwidth delivery and high Quality of Service (QoS) placed Fiber optics above wireless connectivity in
their overall performance.
Due to an explosion of demand for high speed wireless
services such as wireless internet,email,stock quotes and cellular
video conferencing wireless communication has become one of the
important field in modern engineering.Wireless networks are broadly
classified into four different kinds such as wireless lans,satellite
networks,cellular networks and personal networks. In most of the
scenarios WLAN’s systems are based on single hop operation but in
now a day’s significant study has been done on WLAN’s with multihop
operation.In this research article we have studied the various
security issues of wlan especially with respect to bluetooth.wireless
local area networks are different from Wired networks in terms of
cost,security,high reliability,resource
sharing,scalability,communication media etc. One of the important
problem for wireless network is limited frequency spectrum. In now
a day’s wireless local area network consists of multiple stations that
coexist with in a limited geographic jurisdiction and share a common
wireless channel to communicate with each other.This research work
proposes a mathematical model based security issues of wlan by
investigating,design,implementation and performance analysis using
Digital Signal Processing(DSP) Space Time Processing.Space time
processing technology which uses more than one antennas
with an appropriate signaling and receiver methodology
provides a powerful tool for improving the performance of
WLAN’s.

ANALYSIS AND MODELLING OF POWER CONSUMPTION IN IOT WITH VIDEO QUALITY COMMUNI...ijma
Internet of Things applications such as environmental monitoring and healthcare may involve multimedia
communications from IoT devices to humans for decision-making. Therefore, the quality of delivered
multimedia should be in good perceived quality. Higher video quality results into higher energy consumptions due to encoding and decoding processes and as a result, will affect the performance of IoT devices due to their inherent energy constraints. This paper presents the impact of video encoding
parameters as non-network parameters on the energy consumption of IoT devices. The experimental results from Cooja simulator show that the videos with high bitrates and low frame rates consume more power than videos with low bitrates and high frame rates. It was also found that video content type affects energy consumption. Finally, this paper proposes a power model that takes into account video parameters such as
bit rate, frame rate and content types. The proposed model can play a vital role in video quality adaptation in multimedia communication over IoT devices.
Secure transmission in wireless sensor networks data using linear kolmogorov ...csandit
In Wireless sensor networks (WSNs), All communications between different nodes are sent out
in a broadcast fashion. These networks are used in a variety of applications including military,
environmental, and smart spaces. Sensors are susceptible to various types of attack, such as
data modification, data insertion and deletion, or even physical capture and sensor
replacement. Hence security becomes important issue in WSNs. However given the fact that
sensors are resources constrained, hence the traditional intensive security algorithms are not
well suited for WSNs. This makes traditional security techniques, based on data encryption, not
very suitable for WSNs. This paper proposes Linear Kolmogorov watermarking technique for
secure data communication in WSNs. We provide a security analysis to show the robustness of
the proposed techniques against various types of attacks. This technique is robust against data
deletion, packet replication and Sybil attacks
An IOT Based Low Power Health Monitoring with Active Personal Assistanceijtsrd
Among sensible goals of active and assisted living paradigm is the unobtrusive monitoring of daily living activities. A lot of research has been going on continuous home and personal monitoring applications. There are many solutions were adapted by these technologies to make better remote monitoring applications. The traditional continuous home and personal monitoring systems which are implemented with traditional client server architecture which may fail in factors like low power consumption, un deterministic data delivery time, More sensitive to external connectivity issues temporary failures of servers , adhoc networks using ZigBee and Z wave etc. and also increase the cost of implementation. However, when dealing with the home environment, and especially with older adults, obtrusiveness, usability, and cost concerns are of the utmost relevance for active and assisted Living AAL joint program. With advent of cloud services, the continuous remote monitoring based applications became truly plug and play' approach implementation and also reduce the problems of temporary failures. One of the biggest challenges in this area is to make such application devices work with low power battery based applications . The main drawback comes from the higher power consumption, inherently needed to sustain much higher data rates. In this project, a solution is proposed to improve the low power consumption in Wi Fi sensors by making use of advanced RF based Microprocessor from Texas instruments CC3200 . Bed Occupancy sensor automation has been designed and implemented to test the feasibility of the approach. The TI CC3200 comes with ARM Cortex M4 as a core and inbuilt Wi Fi subsystem. The CC3200 provides different power modes to make the device enter into sleep or hibernate mode. This device will only enter only in work phase when the sensor is active state. During this phase, the processor sample and processes the sensor data and uploads to the cloud using REST API. Thing speak is an IoT cloud service used to present the sensory data as graphs, bar charts, and dashboards on the cloud remaining time it will enter into sleep phase to save the power of the device, so that it will extend the battery life time of the device.

Efficient Data Aggregation in Wireless Sensor NetworksIJAEMSJORNAL
Sensor network is a term used to refer to a heterogeneous system combining tiny sensors and actuators with general/special-purpose processors. Sensor networks are assumed to grow in size to include hundreds or thousands of low-power, low-cost, static or mobile nodes. This system is created by observing that for any densely deployed sensor network, high redundancy exists in the gathered information from the sensor nodes that are close to each other we have exploited the redundancy and designed schemes to secure different kinds of aggregation processing against both inside and outside attacks.
International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.
A decentralized paradigm for resource-aware computing in wireless Ad hoc netw...TELKOMNIKA JOURNAL
A key factor limiting the democratisation of networked systems is the lack of trust, particularly in the wake of data-intensive applications that work on sensitive and private data, which requires providing strong network security guarantees via encryption and authentication algorithms, as well as rethinking algorithms to compute on the network peripheries without moving data. In many security and privacy-critical domains such as Home Automation IoT networks, AUV networks etc., the existence of a centralized privileged node leads to a vulnerability for leakage of sensitive information. In this paper, we have proposed a decentralized networking architecture that adopts collaborative processing techniques and operates within the tradeoff between network security and performance. We have investigated the design and sustainability of autonomous decentralized systems and evaluated the efficiency of the proposed scheme with the help of extensive simulation tools.

The Abstracted Network for Industrial InternetMeshDynamics
Widespread adoption of TCI/IP protocols over the last two decades appears on the surface to have created a lingua franca for computer networking. And with the emergence of IPv6 removing the addressing restrictions of earlier versions, it would appear that now every device in the world may easily be connected with a common protocol.
But three emerging factors are requiring a fresh look at this worldview. The first is the coming wave of sensors, actuators, and devices making up the Internet of Things (IOT). Although not yet widely recognized, it is beginning to be understood that a majority of these devices will be too small, too cheap, too dumb, and too copious to run the hegemonic IPv6 protocol. Instead, much simpler protocols will predominate (see below), which must somehow be incorporated into the IP networks of Enterprises and the Internet.
At the other end of the scale from these tiny devices are huge Enterprise networks, increasing movingly to the cloud for computing and communication resources. An important requirement of these Enterprises is the capacity to manage, control, and tune their networks using a variety of Software Defined Networking (SDN) technologies and protocols. These depend on computing resource at the edges of the network to manage the interactions.
The third element is a conundrum presented by the first two: Enterprises will be struggling with the need to bring vast numbers of simple IOT devices into their networks. Though many of these devices will lack computing and protocol smarts, the requirement will still remain to manage everything via SDN. Along with this, many legacy Machine-to-Machine (M2M) networks (such as those on the factory floor) present the same challenges as the IOT: simple and/or proprietary protocols operating in operational silos today that Enterprises desire to manage and tune with SDN techniques.
SECURITY AND PRIVACY AWARE PROGRAMMING MODEL FOR IOT APPLICATIONS IN CLOUD EN...ijccsa
The introduction of Internet of Things (IoT) applications into daily life has raised serious privacy concerns
among consumers, network service providers, device manufacturers, and other parties involved. This paper
gives a high-level overview of the three phases of data collecting, transmission, and storage in IoT systems
as well as current privacy-preserving technologies. The following elements were investigated during these
three phases:(1) Physical and data connection layer security mechanisms(2) Network remedies(3)
Techniques for distributing and storing data. Real-world systems frequently have multiple phases and
incorporate a variety of methods to guarantee privacy. Therefore, for IoT research, design, development,
and operation, having a thorough understanding of all phases and their technologies can be beneficial. In
this Study introduced two independent methodologies namely generic differential privacy (GenDP) and
Cluster-Based Differential privacy ( Cluster-based DP) algorithms for handling metadata as intents and
intent scope to maintain privacy and security of IoT data in cloud environments. With its help, we can
virtual and connect enormous numbers of devices, get a clearer understanding of the IoT architecture, and
store data eternally. However, due of the dynamic nature of the environment, the diversity of devices, the
ad hoc requirements of multiple stakeholders, and hardware or network failures, it is a very challenging
task to create security-, privacy-, safety-, and quality-aware Internet of Things apps. It is becoming more
and more important to improve data privacy and security through appropriate data acquisition. The
proposed approach resulted in reduced loss performance as compared to Support Vector Machine (SVM) ,
Random Forest (RF) .

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Statements about the Future I
> It is difficult to make predictions, especially about the future.
(Karl Valentin, Mark Twain, Winston Churchill, Albert Einstein, Niels Bohr etc.)
> Most technologies that will be used widely in 5-10 years
are already existing in a lab today.
We just do not know which of them will be successful.

Evaluation of ICT Research in Norway
Recommendations:
“Research areas are often fragmented and
not well aligned with Norwegian industry.
A bottom-up «free academic»
approach is dominating ….
Although the outcome of this funding
is not bad, coordination is lacking ….
An obvious strategic area is ICT in life
sciences, but also industrial robotics in
dangerous environments such as
off-shore, and cyber‐security.
ICT in Energy and Power Engineering
also seems also an obvious strategic
research area of national interest.”
